The Langmuir probe modeling in ion-beam plasma
The mathematical model of single cylindrical Langmuir probe describing dependence of ion current gathered by the probe on the basic parameters of ion-beam plasma, such as probe potential, cold and beam ion densities, relation between ion and electron temperatures is built. The model covers wide pa...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The mathematical model of single cylindrical Langmuir probe describing dependence of ion current gathered by the probe on the basic parameters of ion-beam plasma, such as probe potential, cold and beam ion densities, relation between ion and electron temperatures is built. The model covers wide parameters range of the ion-beam plasma, particularly the whole range typical for technological ion-beam systems. The results of numerical calculations are presented for the probe current versus probe dimensions and potential as well as the plasma parameters. The analytical expression for the ion current (modification of the Bohm formula) is derived for the large probe limit. For the numerical results the approximation formula is constructed, simplifying practical usage of the results. |
